Transpacific (North Pacific)
A great-circle route across the North Pacific, exposed to hurricane-force winter storms from October to April.
North America · sea freight from Qingdao
Qingdao to San Diego
Yellow Sea · Korea Strait · Sea of Japan · Tsugaru Strait · North Pacific
This route runs out of Qingdao on the Yellow Sea, where April to July is fog season, then follows a North Pacific corridor with no canal or chokepoint; at the far end is the port of San Diego.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
Route profile
A great-circle route across the North Pacific, exposed to hurricane-force winter storms from October to April.
Two filings before loading, a Section 301 line set by classification, UFLPA supply-chain questions and a 15-day General Order clock after discharge.


Where this route gets difficult
They run from the Qingdao terminal through the voyage to San Diego and the United States import file.
Shandong MSA has issued a waterway safe-transport guide specifically for lithium battery energy storage systems at Shandong coastal ports, so ESS units shipped from Qingdao should be prepared with that provincial guide in mind as well as the IMDG Code.
What Anxin does: For ESS cargo we review the unit's packing and securing plan against the Shandong guide with the packing site before booking.
NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.
California has added battery-embedded products to its electronic-waste program: from 1 January 2026 buyers pay a recycling fee at purchase, and each covered product must show the manufacturer's name or brand and the battery chemistry (or put it on the maker's website), with an annual product notice to CalRecycle and retailers.
What Anxin does: If the goods landing at San Diego are devices with built-in batteries for sale in California, we ask the brand owner to confirm the chemistry labelling and the CalRecycle notice before shipping.
A container landed at San Diego without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at San Diego, and chase any missing invoice or HTS detail while the ship is still at sea.
US importers, like manufacturers and retailers, must tell CPSC within 24 hours once they have information reasonably suggesting that a consumer product fails a safety rule or has a defect that could create a substantial hazard. Battery overheating reports from customers can trigger that duty, and CPSC expects any investigation to take no more than about 10 working days.
What Anxin does: We keep the manufacturer's batch records, UN 38.3 summaries and packing photos for each shipment to San Diego, so the importer can answer CPSC questions quickly.

Documents & compliance
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

We line up UN numbers, model names and package counts across the Qingdao filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at San Diego.
Carriers we book with
Our booking panel; availability on this lane and acceptance of the declared UN numbers are confirmed for each booking. It does not mean that a listed carrier runs a direct service on this route. Carrier choice depends on the trade lane, cargo classification and each carrier's dangerous-goods acceptance at booking. The final carrier is confirmed on the booking.
Risk & mitigation
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Heavy-weather damage in a winter storm | North Pacific, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
Questions
Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.
Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.
Mainly April to July, according to the China Meteorological Administration, which calls sea fog a major hazard for Yellow Sea transport.
